In general, the word supplement refers to anything added to your diet to make up for a nutritional deficiency. While supplements like the iron and folic acid tables, calcium or multi-vitamin tablets are still quite common, the term has also come to refer to all sorts of bodybuilding supplements taken by gym-goers to enhance their physique and reach their goals faster. There’s a lot of information on supplements on the internet these days and TheHealthSite.com tries to separate the wheat from the chaff, the good ones from the dangerous ones.
